On September 15th, the "Scientific Exploration Award", one of the most domestic youth science and technology talent funding plans, announced the award list. Professor Wang Haohua, a School of Physics, Zhejiang University, was ranked among them, winning 3 million yuan.

Super -guided quantum computing and quantum simulation experiments are Wang Haohua's research direction. Two months ago, he cooperated with his colleague Wang Zhen and the Deng Dongling Research Group of the Tsinghua University Cross Information Research Institute. Published on the top international journal "Nature".

What is time crystal? The crystals we are familiar with daily, such as salt, ore, etc., which constitute their atoms in space arrangement of a certain periodic change; and time crystals try to expand the characteristics of "crystals" to the time dimension. A certain periodic change.

"Have you seen" Star Trek "? The" five -dimensional space 'after the protagonist enters the bookshelf. Here, the time becomes a three -dimensional existence, and it is constantly returning to the ring. Don't leave the earth and accompany your daughter. "In an interview with the media, Wang Zhen worked hard to explain the concept," This is an imagination of the time crystal '. "

Through the full digital quantum simulation, the research team successfully simulated a chain topology time crystal composed of 26 "quasi particles" for the first time. Through the modulation system disturbance, the experiment successfully described the boundary between the topology and the mediocre and thermalization. This is a bit similar to a row of children listening to the headset. Even if the rhythm of music changes, you can still observe that there are stable "tacit understanding" of two children and tails, and periodic echoes are performed periodically.

It is worth mentioning that the "Tianmu No. 1" super -guided quantum chip self -developed by the Hangzhou International Science and Technology Innovation Center of Zhejiang University, Hangzhou International Science and Technology Innovation Center, is also participated in the development of Wang Haohua's research team. On the day, the world's first user -oriented, the superconductant quantum computing cloud platform, which supports multiple quantum computers, supports the parallel scheduling of multiple quantum computers, is also the figure of Wang Haohua's team. The platform can currently provide a maximum 36 bit computing power support, and the amount of computing on specific issues is 1,000 times that of personal computers.

Turning back to the end of 2010, Wang Haohua left the top superconductant quantum computing group in the United States. It became a professor through the "green channel" of Zhejiang University, and could not be subject to performance evaluation indicators for a period of time. He once said: "This policy has just returned to the country like me in scientific research. It is very positive for young people with a high technical difficulty, long platform construction cycle, high experimental costs, and shortage of supporting facilities. ","

With the support of Zhejiang University, Wang Haohua took the team to make breakthrough progress in the field of quantum computer research. In 2017, I participated in the research and development of 10 Bit super -guide quantum chips, and realized the entanglement of 10 superconductant quantum bits in the world at present, breaking the records that were previously maintained by Google and the University of California Santa Barbara, and in 4 Bit superconductant quantum processor shows the quantum algorithm of the fast -solving linear equation group, which enables my country to enter the international first echelon in the field of quantum computer research.

In 2019, he cooperated with the team composed of domestic units such as the Institute of Physics of the Chinese Academy of Sciences, the Institute of Automation of the Chinese Academy of Sciences, and the Beijing Computing Science Research Center, developed a quantum chip with 20 superconductant quantum bites, and successfully controlled its global entanglement, refreshing The world records of entangled quantum ratio are generated in solid quantum devices.

You know, universal quantum computers can affect or even subvert scientific research and daily life.

For example, during the development of new drugs, in order to find the most effective drugs, chemists usually need to conduct experiments in countless different molecular combination methods. Classic computers are difficult to simulate molecular interaction at the quantum level, but quantum computers can quickly determine one of the most likely effects in a massive molecular combination mode, which greatly saves R & D costs and time.

For another example, the current deciphering password needs to be used for poverty. However, the quantum computers that are good at large decomposition can enter the numbers on each password level "simultaneously" input. The universal quantum computer will decipher the large digital password into a "small dish". At that time, the RSA password used in confidential communication will no longer be a "password".

Native

We have a reason to believe that with the unremitting efforts of Professor Wang Haohua and other scientists, quantum computers can grow up from babies in the cradle.
